Definitions

  • the present invention relates to an information input device that can acquire information input on a booklet-like recording medium in which a plurality of paper sheets are bound.
  • a technology is known that digitizes, stores and manages information that is written on a booklet-like paper medium in which a plurality of paper sheets are bound.
  • a person places a notebook on a pad of a digitizer and writes content by hand using a special pen.
  • the hand-written content is read by the digitizer as image data, and is stored in a memory of a personal computer (PC).
  • PC personal computer
  • the notebook is not fixed to the digitizer. Therefore, positional displacement of the notebook may occur on the digitizer when the content is being written. If the positional displacement of the notebook occurs on the digitizer, reproducibility of the content that is based on the image data read by the digitizer may deteriorate.
  • An information input device is configured to acquire information that is input on a recording medium using a writing tool.
  • the recording medium is in a booklet form in which a pair of cover sheets and a plurality of paper sheets stacked and arranged between the pair of cover sheets are bound.
  • the information input device includes first detecting means, second detecting means, first positioning means, second positioning means, first information acquiring means, and second information acquiring means.
  • the first detecting means is configured to detect a position of the writing tool that is in proximity of the first detecting means.

  • the second detecting means is configured to detect a position of the writing tool that is in proximity of the second detecting means.
  • the second detecting means is connected to the first detecting means via wiring and is a plate-shaped body that is configured to face almost a whole surface of a second cover sheet of the pair of cover sheets.
  • the first positioning means is configured to position the first cover sheet such that almost the whole surface of the first cover sheet faces the first detecting means.
  • the first positioning means is provided on the first detecting means.
  • the second positioning means is configured to position the second cover sheet such that almost the whole surface of the second cover sheet faces the second detecting means.
  • the second positioning means is provided on the second detecting means.
  • the first information acquiring means is configured to acquire information that is written on the paper sheet overlapping with the first cover sheet positioned by the first positioning means, based on the position of the writing tool detected by the first detecting means.
  • the second information acquiring means is configured to acquire information that is written on the paper sheet overlapping with the second cover sheet positioned by the second positioning means, based on the position of the writing tool detected by the second detecting means.

  • the second cover sheet is positioned by the second positioning means such that almost the whole surface of the second cover sheet faces the second detecting means.
  • the information that is written on the paper sheet overlapping with the first cover sheet is acquired based on the position of the writing tool detected by the first detecting means.
  • the information that is written on the paper sheet overlapping with the second cover sheet is acquired based on the position of the writing tool detected by the second detecting means.
  • the pair of cover sheets are positioned with respect to the pair of detecting means (the first detecting means and the second detecting means) that are mutually independent. It is thus possible to suppress the occurrence of positional displacement of the booklet-like recording medium when information is being written on the paper sheet that overlaps with one of the pair of cover sheets.
  • the first positioning means may be provided on a first surface of the first detecting means on which the first cover sheet is arranged, and be configured to position a corner on the free end side of the first cover sheet such that a writable range of the paper sheet overlapping with the first cover sheet corresponds to a detection range of the first detecting means.

  • the holding means may be provided in a position where the holding means does not come into contact with the first fixing means of the first detecting means that has been inserted and held between the first cover means and the holding means. In this case, it is possible to inhibit the holding means from adhering to the first fixing means of the first detecting means.
  • the first detecting means and the second detecting means may be configured to rotate around an axis line extending between the first detecting means and the second detecting means, and may be configured to move in a direction in which the first detecting means and the second detecting means approach each other and in a direction in which the first detecting means and the second detecting means separate from each other, with the axis line interposed therebetween.
